20090066750Forceless support frame for printhead shuttle in digital printers - In a digital printer the elements involved directly in the print process, which are located on a shuttle assembly are mounted upon a metrological frame which is isolated from the base frame by vibration dampers. Because the elements of the shuttle drive systems, such as a belt drive system having a motor and pulleys, are mounted upon the base frame, the drive and reaction forces from the motor drive systems are led to the base frame while the shuttles assembly is guided by the force-free, vibration free metrological frame. This allows for higher accuracy during printing as the metrological frame serves as a vibration free reference element.03-12-2009
20090211469Double shuttle configuration for digital printers - A printhead positioning system is provided wherein the shuttle assembly is split up in a printing shuttle, having a high accuracy positioning capability and a utility shuttle needing only a low accuracy positioning system. Due to this split-up the mass of components which have to be positioned accurately is greatly reduced and therefore making it easier to position the lighter load accurately and allowing for use of cheaper drive systems while maintaining the high accuracy in printing.08-27-2009

20080288114Method and System for Control of a Compliant System - The invention relates to the control of an actuator system comprising an actuator and a load that is connected to the actuator by a drive chain comprising a compliant element. The load is positioned by controlling the actuator, which control of the actuator comprises at least the feeding of one or more reference signals to the actuator. To compensate for drive chain compliancy the invention proposes to generate a main reference signal component based on performance specifications of the system and to generate an additional reference signal component, which is adapted to compensate for predetermined jerks induced in the actuator system by the main reference component. The main reference signal and the additional reference signal are superimposed and fed to the actuator.11-20-2008

20110179431LINEAR MOTOR FOR LASER BEAM RECORDER - A linear motor for a laser beam recorder for mastering of optical media. The linear motor has a base and an actuator, the actuator being mounted to the base in a flexible way, such as via a leaf spring. The actuator may have a balance mass as a counter mass. The balance mass is preferably formed by an essential component of the linear motor.07-21-2011

20110159797Quiet System Cooling Using Coupled Optimization Between Integrated Micro Porous Absorbers And Rotors - Micro porous absorber structures that be tuned to attenuate noise at the blade pass frequency (BPF) of a cooling fan. The absorber may comprises a panel covered with micro-porous openings with an air gap under the panel. The size of the air gap may be adjusted dynamically to optimize noise attenuation for a fan operating at different speeds.06-30-2011

20090002939Systems and methods for fan speed optimization - Systems and methods for controlling cooling fan speed based on ambient noise levels are disclosed. Some embodiments may include a method for controlling cooling fan speed. The method may include receiving an indication of a current ambient noise level at a computer system and predicting noise due to one or more cooling fans at an expected operator position for the computer system based on a first speed of the cooling fan(s). Embodiments of the method may also include comparing the predicted operation position noise due to the cooling fan(s) with the current ambient noise level and adjusting the cooling fan(s) to a second speed based on the comparison between the predicted operator position noise and the current ambient noise level. Other embodiments are disclosed and claimed.01-01-2009
20100079094Enclosure acoustic compensation - In some embodiments, an amplification spectrum for an electronic device enclosure is identified and/or determined to improve a user's audio environment, e.g., by reducing unwanted noise such as fan noise and/or by processing audio signals that have been or will be distorted by the enclosure acoustics.04-01-2010
